The CAMAG Derivatizer is an automated spraying device which sets a new standard of reproducibility in the reagent transfer onto TLC/HPTLC plates by employing a unique "micro droplet" spraying technology (patent pending). The CAMAG Derivatizer ensures homogeneous and reproducible application of the most common reagents. To meet the diverging physicochemical properties of the different reagents, e.g. acidity or viscosity, four different color-coded spray nozzles are employed, and the user can select from six spraying levels.

In addition to the significantly increased homogeneous reagent distribution, the Derivatizer offers other advantages compared to manual spraying:

Derivatization means another step in the process, consequently causing an increase in the variance. If an experienced technician manually sprays, the relative standard deviation of the measured values significantly rises up to 12.0%. In contrast with the CAMAG Derivatizer, the standard deviation slightly increases between 2.5 and 4.5%. Moreover, these results are user-independent and reproducible!

The following most common reagents have been tested and validated by the CAMAG laboratory for use with the CAMAG Derivatizer:

Sulfuric acid reagent (10 % in methanol)

Anisaldehyde reagent

Natural product reagent

Polyethylene glycol solution

Iodine solution (0.5% in ethanol)

Dragendorff reagent

Fast blue salt B reagent

Ehrlich’s reagent

Phosphomolybdic acid reagent

Ninhydrin reagent

Copper (II) sulfate reagent

Aniline-diphenylamine-phosphoric acid reagent

Vanillin reagent

Potassium hydroxide solution (5% in methanol)

Aqueous solutions (enzymatic solutions, etc.)

The CAMAG Derivatizer is available for two different plate formats (20 x 20 and 20 x 10 cm).
